SASH-LOCK.

SPECIFICATION forming part of Letters Patent No. 348,696, dated September 7, 1886,

Application filed June 29. 1886. Serial No. 206,653.

To all whom it may concern.-

Be it known that I, PI-IILIPP SEILER, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Sasli-Locks, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to devices for securing the meeting-rails of the upper and lower sashes of a window when closed, and it has been my object to produce a fastening that, with closing the window, will be self-locking, and that, after being locked, enables the contracting of the sash one against the other, to form a close joint, that will exclude the entrance of cold air, and will prevent rattling during stormy weather.

My invention therefore consists of the novel devices and combinations of devices hereinafter described and specifically claimed.

In the accompanying drawings, Figure 1 represents a sectional plan of the device in position, having automatically locked the sashes after closing the window. Fig. 2 is a similar view, the latch being secured on its out-of-contact position, for clearing entirely the upper sash; and Fig. 3, a similar View again with the latch-hook moved to clamp the meeting-rails of the sashes against each other. Fig. 4 is an end view of the hook-plate for the upper sash; Fig. 5, an end view of the sashlock; Fig. 6, a vertical section on line 6 6 in Fig. 1; Fig. 7, a bottom view, and Fig. 8 a plan view, of the latch detached; and Fig. 9, a plan and edge view of the latch swinging and shifting lever.

Corresponding letters in the several figures of the drawings designate like parts.

A denotes the plate, secured upon the lower rail of the upper sash, that has a rigid hook, a, and B is the lock-plate secured upon the and shaped like the zone of a circle, with a tubularstem, b, in its center, which is round at its base and end and squared at its middle portion. This plate B is also provided near its periphery with a lug, c, and with a segmental ridge, d, that at its rear end forms an inclined shoulder, and upon its forward end the plate B has a lug, o.

E is the latch, consisting of a hook having (No model.)

a circular hub, that is cored out in its bottom to form a socket having parallel faces 6 and e, which are perpendicular to the shank of the hook part. The hub has also an L-shaped socket, f, in which is secured the end of a spring. Through the center of its hub the latch E has an eye, 9, which is oblong on the line of the hook-shank, to afford asliding motion in that direction on its pivot; and to its rear lower edge is formed a nose, 12, adapted to engage with lug c. This latch E is placed upon plate B, with the end of stem b entering the eye 9 of the latch-hub to be flush therewith, and a rosette-shaped washer, j, secured on top of stem 1) by a rivet, i, holds the parts together.

Upon the lower round part of stem bis pivoted the hub of a lever, L, which has formed to each side of its pivot-eye a cam projection, I, both cam projections being diametrically opposite each other on a line perpendicular to the center line of the lever. This lever is somewhat curved, to afford a slight rocking movement, sufficient to its passing over segmental ridge (1 and then to be engaged behind the inclined shoulder thereof. The wall at of the socket part of latch E is sufficiently cut away to clear the leverL where it projects from under, and to allow it a free swing of about one-quarter of a revolution.

Upon the square portion of stem 1) of the plate Bis secured the inner end of a coiled spring,'N, the outer end of which is hookshaped, and is engaged with the L-shaped socket f of latch E, in a manner that this spring N will exert its elastic force to push the latch E toward and against lug 0, which limits the movement of such latch. \Vith closing the window, the latch E, when brought in contact with the hook a by sliding over the beveled end thereof, will be pushed sidewise, to clear such hook, and will then be swung by the spring to engage under such hook a, so as to be self-locking. The lever L not only forms the handle by which the latch E is turned out of engagement with hook a for opening the window, but by swinging it farther in the same direction until such lever L engages behind the end shoulder of segmental ridge (1, the latch can be locked on a position entirely clearing the upper window-sash, which will be found particularly desirable for washing the windows, for which purpose the positions of the sash are frequently reversed; and after the latch E has been locked with hook a, by turning lever L in the direction toward such latch-hook, its rear cam, I, will be brought in contact with face a of the socket of latch E, and will shift the latch rearward, whereby the hook of such latch will engage the shank of hook a, and will clamp the meeting-rails of the sash against each other, and whereby the nose h, otherwise clearing lug 0, will be moved behind such lug c, that then will form a stop or shoulder against turning engagement with hook a.

WVhat I claim is 1. The combination, with hook a, of swinging latch E, having a hook to its end and being provided with a spring, N, and lever L, for self-locking and for clamping the sash, sub stantially as and for the purpose set forth.

the latch out of 2. The combination, with hook a, of latch E, with spring N and lever L, adapted to engage with the shoulder of ridge d, substantially as and for the purpose set forth. 25

3. The combination, with plate A and hook a, of hook -latch E, pivoted upon stem b of plate 13, of spring N, and lever L, having cam projections Z, substantially as described, to operate as specified. 3o

4. The combination, with plate A and hook a, of latch E, having nose h and pivoted upon stem 1) of plate B, having lu'g c, and of spring N, and lever L, with cam projections Z, all substantially as described, to operate as speci- 3 5 fied.

In testimony whereof I affix my signature in presence of two witnesses. l
